Yes! Genetically engineered animals. As I'm coming from biotechnology background, these things are quite old for me. You may like to know about designer human babies too.
I have heard of Liger before. Mix of lion and tiger. For other, this is the first time I know about it. Leopon....What a name. Lol!!
I am familiar with the liger also, but the other two in the list looks pretty strange but facinating.
Hope all of them were real. There is every possibility of gene mixing to get these wonderful mixture of species.
Sometimes biotechnology scares too much. I saw an image of a dogman. That was really crazy. But if we say about these ones, they look cool.
I remember seeing a show on channel 5 recently where these animals were mentioned. It was called Nature Shock and it was about this bear that had been shot in the very north of Canada and when the guy shot it he thought it was a Polar Bear, but it turned out to be a hybrid of a Polar bear and a Grizzly bear. It was the only known natural hybrid in existence (too bad he shot it).
I've heard of Liger before but the rest, I'm not familiar or heard anything about it before. Good find!
